Specifications of C-Orientation Alnico Magnet
Grain alignment of C-orientation alnico magnet is follows the curved profile of the C-shaped body, it's magnetic flux travels along the continuous curved path inside the magnet, with north and south poles at the open end faces and flux closing along the arc length.Its core advantages are uniform flux, low thermal drift, good resistance to self-demagnetization, and long-term field stability . It is widely used in precision instrumentation, percision moving-coil sensors, ammeters, inertial instruments, magentrons, traveling wave and aerospace.
| Performance Items | C-Orientation Alnico Magnet | Horseshoe Orientation Alnico Magnet |
| Grain Anisotropy | Curved / arc-shaped orientation | Linear axial orientation (separate alignment for two legs) |
| Peak Air-gap B | Relatively low | Higher |
| Air-gap Field Uniformity | Wide-range uniformity | Concentrated on the axis, narrow uniform zone |
| Risk of Self-demagnetization | Low,capable of long-term operation without a keeper | High, prone to demagnetization in open circuit, keeper usually required |
| Magnetic Leakage | Low internal magnet leakage | Relatively high leakage at corners & side edges |
| Primary Target Application | Uniform magnetic field, long-term stability, low drift, Ideal for moving coils, magnetic damping, sensors | High pull force, high peak air-gap flux, Suited for magnetic holding |
